Abstract

[0002] For surface protection coatings, the uniformity, thickness resistance, glossiness and other indicators of the coating are very strict. The production process of surface protection coatings is to mix powder and filler particles into liquid base materials. The base materials are mainly various solvents to form a uniform and fine suspended dispersion. The coating powder and filler particles are very small and aggregate into large secondary particles during the mixing and dispersion process. At this time, it is necessary to use dispersing or grinding equipment to de-aggregate them, form stable molecular particles, and evenly disperse them in the solvent.
